Be it known that el. l'luxs'r S'ruassnt'n- GER, a Citizen ol' (jermanv` residint* in (.hixago, Cook county, Illinois. hartin'vent'ed certain new and useful lmirovements in the (`onstru'tion of Pliers, whereol the follt'm'ing is a full and ('orreet 'let'ilieatitm, reference being'had to the hereto aeeomrzurving' drawng, formintr a jtart hereol' and in vwhich- Figure 1 shows my said new deY'it-e inside \"iew; lifig. 2 shows the same turned and the leg's broken away, short. lfit'. shows the inside view of the t'onstrut'tion of one `1aw. and 141g. '-l shows the inside ('onstruetlon of the opyosite jaw of my said-( levit'e. llfig. 5 shows the end or top view ol" l"i extended fartlie'r down towzird the 'pivot Fig. 6 shows the end view of lfig. 4, also extended farther down toward the pivot. lfigs. 3

:lud i show onl the workingr part of eaeh jaw, the other ''arts heingr hrolten away. Fig. 7 shows the jaw end ot said instrument applied to the worh 'I'or whieh it is speeially designed. l `i,". 8 shows a fragment' oll a. lrunless eye-glass and its att'aelnnent', m side view.

lt is a well known faetV that metal attachinenls to rimless `leuses of spet'tat'les het'oine loose, easily, and that it is more or less lahorious to re-lit said 1:: 'ts so that they shall hold properly and so that bo o\"ereo.ine. With o'rd for sueh work and, therelore, are the frequent hrealtage ol' sueh lenses.

The ohjeet of my invent ion is to orereoine said ilillieulty. To attain said desirable end I make a pair ol` piiers of special construction 'and well adapted directly to overeoine said i I provide an ordinary pliers o with two speclally ('.mistrueted jznv-menihers and z' Whereof the special ('onstriu't ion ofsaid parts is, more 1m-rtiteularly. at their extreme ends.

ns will be made elea-r in showing their art ual use.

The aw l) is seniiylintlrieal. externally, and at, internally, and rrovided w't h a central noteh 'or Lfroo've (l, and the ;aw r is all looseness shall The said work is now done` inary pliers, which are not well litted eause of f sullit'ient ly. after wl a.eoniparati\'el thin member. t'oneaved internally and eonrexed externally, as .shown in l'ies. z'r and i'n whieh the former shows the interior eonstruetion, and tln` latter shows tht'I same iu end view, as seen in lookin to\\'a'rd its outer end, a `greater length of jaw being' shown in the latter than in the l'ormer' lig.. and said part. is 'provided "'ith a ret'tangiilartv sha'ped noteh e ('ut through from side to side. as shown. The jaw c is somewhat longer than its opposite member I), as eleal'ly shown in Figs. the latter l"i,r. the 'reason for such added length is t'learly apparent, the glass is relieved from all strain and, eonsetniently.

- from all danger of breaking.

Thenoserieeef' of riinless` eyeglasses is provided with a ('lainp f at eat'h end and fromsaid t'lanrp extend arms'f whieh lay on the edge of the lenses 'i to rre'vent tht` ntotion of the elanip or elanips f around the serew (1 which ('auses said looseness. 'ith my said new pliers said looseness is quiekly and entiretwj overt'ome by applying them as shown in liig. 7. Preferahly. the st'rew t/ is loosened before the instrument is a'l-ziilied, then the jaws of said instrument are shut against the iznv-hlade f* and t'onuiressed lirml \I enough to shorten or iu set said blade ut'h sa'i'l st'rew is .gain driven home.

'l`he essential features of my said structure arel the shorter jaw with an internal nott'h (l to hold the workjlroin slipping or injur and the longer jaw with an end notch adapted to leave untouehed the ('entral rib o r ridge o'l' the nose-pieee- "hat vi elaiin is:

' Pliers whereof one jaw-member is 'vided with a noteh forming a longitudnal channel in the fat-e toward the opposite jaw and said o,''posite jaw providedwith an end noteh eut through the .member so as to leave two short prong's.
